run code in 300+ PHP versions simultaneously
<?php class A { private function foo() { echo "success!\n"; } public function test() { $this->foo(); //static::foo(); } } class B extends A { /* foo() will be copied to B, hence its scope will still be A and * the call be successful */ } class C extends A { private function foo() { /* original method is replaced; the scope of the new one is C */ } } //$b = new B(); //$b->test(); $c = new C(); $c->test(); //fails

Here you find the average performance (time & memory) of each version. A grayed out version indicates it didn't complete successfully (based on exit-code).
